The Science of How the Coronavirus Spreads

This video illustrates droplet clouds, and how they can move much farther than 2 meters without falling
This video illustrates research done around droplets, droplet clouds, and how they might infect people
Researchers measured the velocity of coughs. Even a meter away from the mouth, droplets in the center of the cough cloud are moving at about a meter per second (green). These speeds suggest keeping six feet distance from other people may not be enough to prevent the virus from spreading in a cough.

Note: This is just one measure of whether masks work or not. There are many more measures. For a much more thorough review, see the paper: https://www.preprints.org/manuscript/202004.0203/v1

Everybody should wear a home-made mask: You can infect other people before you know you’re sick.

Note: don’t use vacuum cleaner bags. They can release tiny glass shards that you can later inhale.
